grinder faults of distinguishing method

Grinding machine is the use of grinding tools on the surface of the workpiece grinding machine. Grinding machine for a long time, a brief presentation of some problems, what are the ways to eliminate problems

(1) Intuitive method: that is to use human senses to pay attention to the appearance of the disease and identify the possible parts of the disease. If there is a problem, where there is abnormal sound, spark attack, where there is a burnt place, where there is an abnormal appearance of fever, and then further investigate the appearance of each circuit board that can attack the disease. This is the most basic and simple method, But it needs grinder maintenance personnel to have certain maintenance experience

(2) Use the hardware alarm function of the grinder: the alarm indicator can identify the fault location. There are many alarm indicators on the hardware circuit board of the grinder, which can roughly identify the fault location

(3) Make full use of the software alarm function of grinder: CNC system has the function of self diagnosis. In the system operation time, self diagnosis program can be used to quickly diagnose the system. Once a fault is detected, the fault will be displayed on the mode screen or the alarm lights will be turned on immediately. During maintenance, the fault location of grinder can be found according to the alarm content

(4) The diagnosis function of condition display: the grinder can not only display the fault diagnosis information, but also provide various conditions of the grinder diagnosis in the form of diagnosis address and diagnosis data, for example, the input / output signal condition of the interface between the system and the grinder, or the input / output signal condition of the interface between PC and CNC equipment, or between PC and grinder, You can use the display screen to see whether the grinder has input the signal to the grinder, or whether the switch information of the grinder has been input to the grinder. In general, you can distinguish whether the fault is on the grinder side or on the grinder side, and then you can reduce the inspection scale of the grinder fault

(5) The grinder parameters should be checked in time when the fault occurs: the change of system parameters will directly affect the function of the grinder, and even make the grinder break down, and the whole grinder can not work. The external disturbance can lead to the change of single parameter in the memory. When the grinder breaks out some incredible faults, the grinder parameters can be checked.
